Otherwise, some experimenting suggests that PythonPlot.jl works very nicely. It's a bit picky about the backends (have not yet managed to get qt5 working, although I don't have problems with that on PyPlot.jl)
Please open a separate issue about the qt5 backend. (Note that PyPlot.jl automatically installs pyqt5 for you if you want this backend, whereas PythonPlot does not.)
Just to have it recorded: https://github.com/JuliaPy/PyPlot.jl/issues/532#issuecomment-936126035 applies to PythonPlot.jl too
